The restaurant is styled after McDonald's, and is known for its red and yellow colour scheme and meat pies. Mr. Bigg's history begins with the coffee shops inside Kingsway Department Stores in the 1960s. In 1973, these shops were rebranded as Kingsway Rendezvous, which became Mr. Bigg's in 1986. The chain saw rapid expansion after becoming one of the first Nigerian companies to sell franchises to investors.

Mr. Bigg's specialty is the meat pie. A common lunch might also include scotch eggs, a sugared donut, chicken, and a soft drink. While western fare such as hamburgers are served, Nigerian delicacies such as jollof rice and moin moin are more popular. Birthday cakes are also a popular product, and Mr. Bigg's bakery offers cakes and pastries.
